Description
Summary:Highly stretchable devices have garnered interest in medical devices and sports equipment due to their ability to capture physiological data. This letter introduces a paper-based highly stretchable corrugated sensor fabricated through inkjet printing. For the fabrication, we used our paper self-folding technique. This technique utilizes the reaction between the paper and the solution to automatically form the origami structure without external energy. This technology imparts elasticity and rigidity to the paper material and enhances its stretchability, repeatability, and motion-tracking ability. The sensor is paper-based, disposable, lightweight, and economical. The sensor demonstrated practical sensitivity and extraordinary stretchability (up to 1507%), coupled with repeat stability of over 1000 cycles, making it an ideal solution for applications requiring durable and reliable monitoring under extreme mechanical conditions. In the final test, the sensor was attached to the body to monitor knee motions and abdominal breathing, showcasing its utility as a wearable biomonitoring device.
